I doubt it mate, on the basis that they've probably sold it as a UK model (referring to its spec), rather than an actual UK car.
I'm pretty sure mine is an import too, as VW had trouble in locating my vin/chassis number when setting up the Volkswagen Assist thingy.
Mine is UK Spec, covered under the Volkswagen assist and warranty, and I have no prob's with my local dealer. Providing there's a healthy difference between what you paid and what a UK dealer would have charged you, you're onto a winner!
